MY 2017 ACO Reporting Overview 1 Overview This document is a set of guidelines for MY 2017 (Year 1) ACO Reporting, which is a new initiative undertaken by IHA. IHA will be soliciting feedback on the efficacy of these guidelines from participants throughout year 1 in order to revise and enhance these guidelines in future reporting years.the following overview and reporting guidelines are specific to IHA s ACO measurement program. Health plans and physician organizations should refer to the MY 2017 Value Based Pay for Performance Manual for ACO measure specifications and General Guidelines. The reporting guidelines outlined here are for anything specific to reporting the ACO measures. IHA/PBGH ACO Reporting Background California is on the leading edge of provider payment innovations, such as accountable care organizations (ACOs), and performance measurement and benchmarking initiatives to foster better care, better health, and smarter spending. At the same time, performance measures have proliferated nationally, increasing demands on providers and potentially challenging efforts to advance high-value care. To make performance measurement more meaningful and less burdensome, IHA and the Pacific Business Group on Health have partnered to develop a standardized performance measurement and benchmarking program for commercial ACOs in California. The goal of the IHA-PBGH partnership is to develop and implement a standard measure set for commercial ACOs that meets the needs of participating purchasers, health plans, and providers while advancing national efforts for coordinated, meaningful performance measurement that promotes high-quality, affordable, patient-centered care or high-value care. The following plans are currently participating in ACO reporting: Aetna Anthem Blue Cross Blue Shield of California Health Net ACOs also have the option to voluntary self-report, similar to the PO-self reporting in the VBP4P reporting. Key Organizations Involved in Data Collection, Aggregation and Reporting IHA NCQA PBGH The Integrated Healthcare Association manages the VBP4P, Medicare and ACO reporting programs and convenes all relevant committees. IHA arranges for all necessary services, including measure development, data aggregation and publication of the results in a public report card. The National Committee for Quality Assurance develops and maintains the clinical measures. The majority of clinical quality measures are adapted from the NCQA Healthcare Effectiveness Data and Information Set (HEDIS) 1 measures, the most widely used set of performance measures in the managed care industry. Non-HEDIS measures are noted in the specifications. NCQA is a nonprofit organization committed to assessing, reporting on and improving the quality of care provided by organized delivery systems. The Pacific Business Group on Health has partnered with IHA to create a standard measure set for use in performance measurement of commercial ACOs. 1 HEDIS is a registered trademark of the National Committee for Quality Assurance (NCQA).

2 MY 2017 ACO Reporting Overview TransUnion HealthCare Onpoint Health Data TransUnion HealthCare (formerly the Diversified Data Design Corporation, a subsidiary of TransUnion LLC), helps IHA collect clinical data from POs and health plans. Onpoint helps collects and standardizes claims, encounter and eligibility data from health plans; aggregates data across health plans for each PO and calculates the ACO measures; and creates reports for all parties. ACO Data Collection and Reporting Timeline The timeline includes major milestones in the ACO data collection and reporting processes, which leverages the VBP4P and Medicare reporting timelines.

6 MY 2017 ACO Reporting Overview 1General Guidelines for 2BData Collection and Reporting For MY 2017 ACO Reporting Health Plans and Self-Reporting POs

MY 2017 ACO Reporting Overview 7 General Guidelines for Data Collection and Reporting The reporting guidelines outlined below are specifically outlined for reporting ACO measus by health plans (through Onpoint) and self-reporting ACOs. Most of the General Guidelines from the Value Based Pay for Performance program apply, as referenced below; any guidelines that differ for ACO reporting are noted here. Please note that references to self-reporting physician organization or PO have been replaced throughout with reference to self-reporting ACO or ACO. For those guidelines that reference back to the VBP4P guidelines, guidelines referencing self-reporting POs or POs apply to self-reporting ACOs for ACO reporting. Reporting Options 1. Two Data Sources Health plan claims submission Self-reporting ACO For all ACO measures, participating health plans submit to Onpoint member-level enrollment, claims and encounter files for all ACO contracts, including an ACO identifier along with the member eligibility file. Onpoint applies the ACO measure specifications and produces the ACO contract results. A PO may self-report data for the ACO population, collecting and submitting administrative results directly to the TransUnion for any or all clinical measures. A self-reporting ACO submits ACO results for all commercial ACO members belonging to a participating health plan, based on the health plan member eligibility file. For MY 2017 ACO reporting, no audit is required. An audit may be required in future reporting years. ACOs that intend to self-report in the coming year should indicate this in the annual intentions survey in November. ACOs can download the ACO Reporting File Layout and from the IHA website in January (final files available in February), and submit unaudited data files to TransUnion according to the timeline specified in the Overview. Electronic data only Regardless of data source, IHA requires that only electronic data (automated claims and encounter data and auditor-approved supplemental administrative databases) be used to calculate the measures. Sampling and the HEDIS Hybrid Methodology may not be used to collect data for ACO reporting. For MY 2017, no audit review is required for ACO reporting. 2. Reporting Level Refer to General Guideline 2: Reporting Level in the MY 2017 VBP4P Manual. Encounter/Claims Submission 3. Submitting Data Refer to General Guideline 3: Submitting Data in the MY 2017 VBP4P Manual. ACO Reporting Policies 4. Not applicable for ACO Reporting

8 MY 2017 ACO Reporting Overview 5. VBP4P Consent to Disclosure Agreement ACOs need to sign the Consent to Disclosure Agreement to confirm their participation in ACO reporting. 6. ACO Definition and Attribution For the purpose of IHA-PBGH Commercial ACO Measurement & Benchmarking Initiative, IHA is defining accountable care organizations broadly. In year 1 (MY 2017) IHA will include any arrangement a participating health plan identifies as an ACO. We'll document these definitions and use them to inform subsequent discussions and decisions about standardizing ACO measurement. All participating plans will use their own definitions of ACO, as well as their own attribution methodologies, with the understanding that the models differ. IHA will document ACO models during MY 2017 data intake and assess appropriate benchmarking. There are three key distinguishing features of ACOs identified that are seen as relevant to the interpretation and benchmarking of results: ACO participants (e.g., 2-way, 3-way, or 4-way contract between health plans, POs, hospitals, pharmacy, and/or purchasers) Payment/incentive structure (e.g., financial risk arrangements) Product line (e.g., HMO, PPO, FFS) The below table outlines the information that each participating plan will be asked to report to IHA: Required ACO Documentation ACO type Member assignment Timing Attribution provider definition Attribution coverage Attribution provider exclusivity Attribution methodology Attribution basis Attribution period Attribution frequency Example HMO 3-way agreement (plan, physician organization, hospital) HMO global risk HMO dual risk PPO 3-way agreement (plan, PO, hospital) PPO 2-way agreement (plan and physician organization) HMO/PPO 4-way agreement (plan, PO, hospital, employer) Attribution algorithm Patient selection Plan assignment Employer assignment Retrospective Prospective PCPs including OB-GYNs PCPs excluding OB-GYNs PCPs and specialists (non-surgical) All members are assigned (except HMO) Some members left unassigned Member assigned to only one provider Plurality provider with most visits Temporal proximity provider with most recent visit Hybrid mix of both E&M visits All visits 12 months 18 months 24 months Monthly Quarterly

MY 2017 ACO Reporting Overview 9 In addition to the above information, IHA will also collect information on the target population of the ACO, in order to understand the potential impact on performance. For example, some ACOs may be formed to address specific populations or care models (e.g., high cost members, specialists managing chronic conditions). Documenting these methodologies and the rationale behind them will help inform any variation seen between ACOs for MY 2017 reporting. IHA will collect this information from both the plans and the ACOs. 7. Not Applicable for ACO Reporting 8. Risk Adjustment Refer to General Guideline 8: Risk Adjustment in the MY 2017 VBP4P Manual. 9. Reliability Testing/Minimum Number of Observations Refer to General Guideline 9: Reliability Testing/Minimum Number of Observations 10. Eligible Population The eligible population for any measure is all members who satisfy all criteria specified in the measure, including age, continuous enrollment (including allowable gap), benefit, event or anchor-date requirement. The rate is calculated using the eligible population after exclusions. For MY 2017 ACO reporting, participating plans will provide an ACO Identifier flag in the member eligibility file provided to the IHA data aggregator. The participating plans will also provide additional information on the effective enrollment segment for the ACO flag. See Guideline 21: Continuous Attribution Periods and Benefits for more information. 11. Optional Exclusions Refer to General Guideline 11: Optional Exclusions in the MY 2017 VBP4P Manual. 12. Product Reporting For MY 2017 ACO Reporting, members are reported for each individual commercial ACO contract, which may be in the HMO or PPO product line. If an ACO member is already included the VBP4P commercial HMO/POS population, also include that member in the applicable ACO population and report. 13. Members Who Switch Health Plans or POs Refer to General Guideline 13: Members Who Switch Health Plans or POs in the MY 2017 VBP4P Manual. 14. Members Who Switch Health Plans or POs as the Result of a Merger or Acquisition Refer to General Guideline 14: Members Who Switch Health Plans or POs as the Result of a Merger or Acquisition in the MY 2017 VBP4P Manual.

10 MY 2017 ACO Reporting Overview 15. Not Applicable for ACO Reporting 16. Members With Dual Commercial/Medicaid Coverage Refer to General Guideline 16: Members with Dual Commercia/Medicaid Coverage in the MY 2017 VBP4P Manual. 17. Members With Dual Commercial Coverage Refer to General Guideline 17: Members With Dual Commercial Coverage in the MY 2017 VBP4P Manual. 18. Self-Insured Members Refer to General Guideline 18: Self-Insured Members in the MY 2017 VBP4P Manual. 19. Members Who Switch Products/Product Lines Refer to General Guideline 19: Members Who Switch Products/Product Lines in the MY 2017 VBP4P Manual. 20. Members in Hospice Refer to General Guideline 20: Members in Hospice in the MY 2017 VBP4P Manual. 21. Members who refuse services Refer to General Guideline 21: Members Who Refuse Services in the MY 2017 VBP4P Manual Required Enrollment Periods and Benefits 22. Continuous Enrollment and Allowable Gaps Continuous enrollment specifies the minimum amount of time a member must be enrolled in the organization before becoming eligible for a measure. The member must also be continuously enrolled in the benefit specified for each measure (e.g. pharmacy or mental health) accounting for any allowable gaps to be considered continuously enrolled. For ACO reporting, the same concept applies, using the participating plans attribution or assignment of members. For reporting purposes, the plan attribution or assignment, as described below, will be used in the same way as continuous enrollment when applying the measure specifications. One of several criteria used to identify the eligible population, continuous enrollment ensures that the health plan or ACO had sufficient time to render services to its members to be accountable for providing those services. The continuous enrollment period and allowable gaps are specified in each measure. For MY 2017 ACO reporting, participating plans will provide an ACO Identifier flag in the member eligibility file provided to Onpoint. The participating plans will also provide additional information on the effective member month or enrollment segment for the ACO flag. This information will be used to identify continuous enrollment to the ACO. The ACO attribution or assignment, as indicated by the member eligibility file and effective member month/enrollment segment, will be used to determine if a member met the continuous enrollment criteria for a specific measure. For example, a member that has an ACO Identifer flag with effective member months dates from January through December 2017 will be considered continuously enrolled in the ACO from January 1, 2017 December 31, 2017, or the measurement year.

MY 2017 ACO Reporting Overview 11 Participating plans will receive an eligibility layout file from Onpoint. The information provided by plans to Onpoint, along with the effective member month date for the ACO flag, will also be provided by the plans to any participating, contract physician organizations that will be self-reporting the ACO measures. The participating physician organizations must use this information to identify the eligible population for ACO reporting and to determine which members meet the continuous enrollment criteria. Using this method, the plans and self-reporting ACOs will have the same denominator for all ACO measures. A gap is the time when a member is not covered by the organization (i.e., the time between disenrollment and re-enrollment). For example, if a member disenrolls on June 30 and re-enrolls on July 1, there is no gap because the member was covered on both June 30 and July 1. If the member disenrolls on June 30 and re-enrolls on July 2, there is a one-day gap because the member was not covered on July 1. With the member month or other enrollment segment flags described above, the gaps will be translated from the enrollment segments provided by the plan. For example, if the plan identifies member month eligibility for January and February 2017, and April through December 2017, the month of March 2017, or 31 days, is considered a gap, because the member was continuously enrolled from 1/1/2017 2/28/17 and again from 4/1/2017 12/31/17. An allowable gap (less than 45 days) can occur at any time during continuous enrollment. For example, the Diabetes Care measure requires continuous enrollment from January 1 December 31 and allows one gap of up to 45 days. A member who enrolls for the first time on February 1 of the measurement year is continuously enrolled if there are no other gaps throughout the remainder of the measurement year (the member had a 31-day gap, January 1 January 31). Enrollment in Medicare or Medicad (FFS or HMO) plan is considered a gap in Commercial enrollment. 23. Continuous Enrollment and Allowable Gaps Over Multiple Years Unless otherwise specified, members are allowed one gap of up to 45 days during each year of continuous enrollment for measures spanning more than 1 year. A gap that extends over multiple years of a continuous enrollment period may exceed 45 days. For example, in the Colorectal Cancer Screening measure (which requires 2 years of continuous enrollment), a member who disenrolls on November 30 of the year prior to the measurement year and re-enrolls on February 1 of the measurement year is considered continuously enrolled as long as there are no other gaps in enrollment during either year. The member has one gap of 31 days (December 1 31) in the year prior to the measurement year and one gap of 31 days (January 1 31) in the measurement year. 24. Anchor Dates If a measure requires a member to be enrolled and to have a specified benefit on a particular date, the allowable gap must not include that date (i.e., the member must also have the benefit on that date). For example, a 55-year-old with only one gap in enrollment from November 30 of the measurement year through the remainder of the year is not eligible for the Colorectal Cancer Screening measure. Although the member meets the continuous enrollment criterion, she does not meet the anchor date criterion, which requires her to be enrolled as of December 31 of the measurement year. 25. Continuous Enrollment for ACOs For each measure, members are assessed for continuous enrollment (attribution or assignment) in the ACO contract. As described in Guideline 21, health plans will provided a membership eligibility file to Onpoint, along with an ACO flag for enrollment segments, to identify continuous enrollment in the ACO. This information will also be shared with the POs that have ACO contracts with the participating plans, for use in identifying the eligible population in each ACO measure for ACO self-reporting.

12 MY 2017 ACO Reporting Overview Determine continuous enrollment using the following steps. Step 1 Step 2 Determine if the member was continuously enrolled (attributed or assigned) to the ACO contract, including allowable gaps.
